The Land Institute is an American nonprofit research, education, and policy organization dedicated to sustainable agriculture, based in Salina, Kansas.

[7] The organization's concept of developing perennial crops is modeled after the ecological design of prairies, which are known for their soil quality, deep root systems, and self-sufficiency.

[11] Since 1979, The Land Institute has annually hosted its Prairie Festival, which includes lectures, art displays, tours, and music performances.

[16][17] Kernza, an intermediate wheatgrass developed by The Land Institute, is the first commercial perennial grain crop grown across the northern United States.

After two decades of plant breeding over 11 cycles, The Land Institute has domesticated a form of wheatgrass whose seeds are two to three times bigger than those of its wild ancestor.

Their "Forever Green Initiative" has attracted interest from large agricultural producers like General Mills and also smaller local food shops like the Birchwood Cafe.

[20] Cascadian Farm agreed to purchase an initial amount of the perennial grain, which is driving farmers to plant on commercial-scale fields versus the test sized plots currently being grown.

The initiative and investment on the part of Patagonia Provisions to bring Long Root Ale to market led to other partnerships and potential Kernza products becoming more widely available to consumers.

The Land Institute's work was featured in Michael Pollan's New York Times best-seller The Omnivore's Dilemma: A Natural History of Four Meals.
